At least one expandable tissue stop is located on one of the first and second jaws and is configured to extend between first and second jaw surfaces on the first and second jaws as the first and second jaws move between the fully open and the fully closed positions.

Systems and methods for securing a tissue site to a sensor

Systems, methods, and apparatuses for enabling non-invasive, physiological sensors to obtain physiological measurements from a region of tissue of a patient are disclosed. Anchoring components can attach to patient tissue sites and sensor heads such that the tissue sites do not move during sensing. Interlocking mechanisms maintain tissue sites within a limited range of horizontal movement and vertical distance from the sensor head.

Alignment fixture for a reactor system

An alignment fixture for a reactor system may comprise a fixture body comprising an inner perimeter at least partially defining a shape which comprises an inner space of the fixture body, wherein the inner space is configured to receive a susceptor of a reactor system; and/or a measuring protrusion coupled to the fixture body at a first position and protruding from the fixture body toward the inner space. The measuring protrusion may comprise an indicator between the fixture body and a measuring protrusion end of the measuring protrusion.

Surgical stapler tool assembly to minimize bleeding

A cartridge assembly for a surgical stapling device includes a staple cartridge that includes a staple array that has a configuration to minimize blood leakage through a staple line formed by the staple cartridge.

Human bioelectrical signal detection and monitoring

The present disclosure includes an electromagnetic field detection and monitoring system. The system includes a single-ended amplifier and an impedance matching circuit which matches the impedance caused by an air gap between tissue and an electrode. The system includes passive detection, active detection, and signal processing capabilities. At least one embodiment includes a body worn system with sensing, processing, communications, and data storage capabilities. The system provides wearable antennas to transfer the EMF energy in its electrical or magnetic forms into the sensor efficiently. A specially designed processing algorithm can process the collected data and generated the results for medical professionals to read and make decisions. The processing can include machine learning technique which decompose an EMF signal into EEG bands to perform feature extraction. The features can then be used to train a machine learning model to classify other EMF signals.

Systems, methods, and devices for automatic signal detection based on power distribution by frequency over time

Systems, methods, and devices for automatic signal detection in an RF environment are disclosed. A sensor device in a nodal network comprises at least one RF receiver, a generator engine, and an analyzer engine. The at least one RF receiver measures power levels in the RF environment and generates FFT data based on power level data. The generator engine calculates a power distribution by frequency of the RF environment in real time or near real time, including a first derivative and a second derivative of the FFT data. The analyzer engine creates a baseline based on statistical calculations of the power levels measured in the RF environment for a predetermined period of time, and identifies at least one signal based on the first derivative and the second derivative of FFT data in at least one conflict situation from comparing live power distribution to the baseline of the RF environment.

INTERACTIVE VOICE CONTROLLED ENTERTAINMENT

Methods and systems for receiving shouted-out user responses to broadcast entertainment content, and for determining the responsiveness of those responses in relation to the broadcast content. In particular, entertainment broadcasts can be accompanied by mark-up data that represents various events within a given broadcast, which can be compared to the shouted-out responses to determine their accuracy. For example, if a game show was broadcast and an individual started shouting out answers during the broadcast, embodiments disclosed herein could utilize a voice-controlled electronic device that captures the shouted-out answers and passes them on to a language processing system that determines whether they are correct by comparing the answers to the mark-up data. The voice-controlled electronic device can also “listen” to background sounds to capture the broadcast of the entertainment content, and send that content to the language processing system, which can use that captured data to synchronize the actual broadcast with the analysis of the shouted-out answers to provide individuals with an immersive entertainment experience.
